Wow dude you are providing so much useful feedback. I love what you think about

When you turn a npc into human/zombie, there will be a chance he can have a random quest for the hero, so the hero can talk to him/her. The idea was to create a random generated quest system in the game, although it's in a very initial state right now.

Currently giving a zombie brains won't increase his favor to you but I think this is a very good intend, I'm thinking about adding it as a new feature.

Thank you for the feedback. If I were right I think you are talking about treasure room, currently there will be a chance that randomly creatures spawn in treasure rooms(rooms that full of money), but it's not guaranteed. Treasure rooms are designed to be relaxing.

Me and my teammate Tapdog have been work on this RoguelikeZombieAdventure demo for a long time.

As in 7DRL we decide to utilize this demo to implement some of our ideas:

Infection and camp-change system.

Random quests.

Gang fights between 3 different camps.

You are infected and your infection increase by time. You will turn into a zombie and start losing HP if you can't control the infection. So you have to take advantage of your form, and struggle a way out of hell.
